Abstract
A plasma production experiment by using an Electron Cyclotron Resonant Heating (ECRH) system has successfully been carried out on the GAMMA 10 linear device. On the experiments, the plasma breakdown has been operated by and built up the temperature and the density by a single 28 GHz/200 kW ECRH system, instead of usual scheme of two plasma guns. We studied the parameter scans on gas feeding level, ECRH wave polarization and ECRH antenna position with 200 kW/10 ms ECRH pulse injection and relayed to the usual Ion Cyclotron Range of Frequency heating sequence. As the result of this preliminary experiment, we could achieve the same level parameters of electron density and diamagnetism, etc. as the usual operational plasma performance like as 5 × 10 19 m −2/7 × 10 −7 Wb.
